基于航线失效的流量重分配策略研究

针对航空网络航线失效情况，基于枢纽航线网络和复杂网络理论，提出了流量重分配优化模型。模型将成本分成航线成本和节点成本，以重分配总成本最小为目标，考虑了非枢纽机场的影响和节点容量，构建了考虑拥堵效应的成本函数，并利用粒子群算法进行求解。最后，以杭州 咸阳航线失效为例进行仿真实验。实验结果表明：提出的模型具有较好的可靠性和有效性，并可以通过调节不同参数影响流量分配成本，提高了模型的可操作性和实践前景。

An Optimization Model for Traffic Redistribution under Condition of the Failure of Airline

To solve the problem of airlines failure, an optimization model for traffic redistribution based on the theories of hub airline network and complex network is proposea. In the model, the cost is divided into airline cost and node cost. Taking the smallest in the total cost of traffic redistribution as a target in consideration of the effect from non hub airport on cost and capacitated constraint, the paper works out a cost function based on congestion. The model is solved by particle swarm optimization (PSO). At last, a simulation is made taking the airline between Hangzhou and Xianyang as an example. The results of the experiment show that the proposed model is good in reliability and in validity. And the operability and practicability can be improved by adjusting these parameters.
